Penyakit Pelupaan @ Forgetfulness @ Dementia

Di sini, aku nak berkogsi ttg penyakit pelupaan @ bak kata mat saleh Forgetfulness. Hasil pemahaman & pembacaan aku ialah, penyakit ini adalah satu penyakit yg ringan utk setiap manusia. Setiap manusia akan mengalami simptom2 ini… Namun, penyakit ini jika tidak dikawal @ dicegah dari awal akan menyebabkan Alzheimer.

Many older people worry about becoming more forgetful. They think forgetfulness is the first sign of Alzheimer’s disease. In the past, memory loss and confusion were considered a normal part of aging. However, scientists now know that most people remain both alert and able as they age, although it may take them longer to remember things. (Forgetfulness: It’s Not Always What You Think)

Agak menggerunkan juga bukan? Forgetfulness ialah

  • Tending or likely to forget.
  • Marked by neglectful or heedless failure to remember: forgetful of one’s responsibilities.
  • Causing one to be unable to remember.

    Women who store fat on their waist in middle age are more than twice as likely to develop dementia when they get older, reveals a new study from the Sahlgrenska Academy.

    The study has just been published in the scientific journal Neurology.

    “Anyone carrying a lot of fat around the middle is at greater risk of dying prematurely due to a heart attack or stroke,” says Deborah Gustafson, senior lecturer at the Sahlgrenska Academy. “If they nevertheless manage to live beyond 70, they run a greater risk of dementia.”

    The research is based on the Prospective Population Study of Women in Gothenburg, which was started at the end of the 1960s when almost 1,500 women between the ages of 38 and 60 underwent comprehensive examinations and answered questions about their health and lifestyle.

    A follow-up 32 years later showed that 161 women had developed dementia, with the average age of diagnosis being 75. This study shows that women who were broader around the waist than the hips in middle age ran slightly more than twice the risk of developing dementia when they got old. However, the researchers could find no link to a high body mass index (BMI).

    “Other studies have shown that a high BMI is also linked to dementia, but this was not the case in ours,” says Gustafson. “This may be because obesity and overweight were relatively unusual among the women who took part in the Prospective Population Study.”

    The study was carried out at the Neuropsychiatric Epidemiology Research Unit as part of the Sahlgrenska Academy’s major research project EpiLife.

    Dementia

    The most common symptoms of dementia are forgetfulness, impaired speech and problems with recognition and orientation. It is a condition that can affect all our mental faculties and which is more common as we get older. Around seven per cent of the Swedish population over the age of 65 and just over 20 per cent of the over-80s have severe dementia..

    Ketika megandung pun, wanita juga cenderung mengalami masalah pelupaan. Kawan2 boleh rujuk kpd artikel ini Forgetfulness during pregnancy. Pengalaman aku ketika peknen pon macam tu juga! Sukar utk mengingati & diingati kadang2. Memang stress giler time tu. Yelah, tak pernah mengalami situasi mcm tu tetiba aku kena…

    Kajian mengenai Forgetfulness is a tool of the brain juga menyokong bahawa penyakit pelupaan ini memang akan berlaku pada setiap manusia :-

    A note to the forgetful: be thankful you don’t remember everything. It means your brain is working properly.

    According to a new study, the brain only chooses to remember memories it thinks are most relevant, and actively suppresses those that are similar but less used, helping to lessen the cognitive load and prevent confusion.

    Brice Kuhl at Stanford University in California, US, and colleagues used functional magnetic resonance imaging (fMRI) to measure the brain activity of 20 healthy adults while they performed a simple memory test. Participants were given three words pairs to memorise, including two pairs that were closely associated, as follows:

    • ATTIC dust
    • ATTIC junk
    • MOVIE reel

    After studying “ATTIC dust” a second time, subjects were asked to recall all three pairs using the first words as cues. On average, people were 15% worse at recalling “ATTIC junk” than they were at recalling the unrelated pair, “MOVIE reel”.

    Initial suppression

    Comparing these findings to the fMRI data taken during the test, the team found participants’ brains were highly active in a region known for handling competing memories, and also in an area believed to induce memory suppression.

    The researchers believe that the first region identified “ATTIC dust” and “ATTIC junk” as conflicting memories. The second region then suppressed “ATTIC junk” because it had only been seen once.

    As the test was readministered a second and third time, suppression activity lessened, indicating the memory adjustment had been made.

    Prioritising memories

    “Whenever you’re engaging in remembering, the brain adapts. It’s constantly re-weighting memories,” says Kuhl. “In this simple test, we see it reverse memory to weaken competing memories. This is something that probably happens a lot in the real world.”

    A good example is the confusion that arises when we change passwords on our computers or email accounts. We often mix up old and new passwords at first, but through repetition we develop a strong memory of the new password and forget the old one.

    “The process of forgetting serves a good functional purpose,” says Michael Anderson of the University of Oregon, US, who was not involved in the study. “What these guys have done is clearly establish the neurobiological basis for this process.”
